All verses are quoted from the NASB anything in [square brackets] is added by me for clarity.

Some people believe that the number of the beast is 6, 6, 6. But they are wrong!

Here is the scripture verse that the number of the beast is mentioned in -

"Here is wisdom. Let him who has understanding calculate the number of the beast, for the number is that of a man; and his number is six hundred and sixty-six." Revelation 13:18

As you can see the number is not six, six, six. It is 600, 60 and 6. It is six hundred and sixty six. What difference does this make?

It definitely makes a difference. On one news group someone wrote and shared the following bit of data -

The word 'world' is 5 letters long and is the 1st word.
5 + 1 = 6.

The word 'wide' is 4 letters long and is the 2nd word.
4 + 2 = 6.

The word 'web' is 3 letters long and is the 3rd word.
3 + 3 = 6.

Therefore the 'World Wide Web' is 666 - the Beast!

Now obviously this is wrong. Even if this was the correct method of calculating the number of the beast. The 1st word would have to be 599 letters long, the 2nd would have to be 58 letters long and the 3rd, 3 letters long.

The number itself is stated in the scriptures therefore it has meaning and significance. So we should use the correct number. Strong's exhaustive concordance says -

5516. chi xi stigmakhee xee stig'-ma the 22nd, 14th and an obsolete letter (4742 as a cross) of the Greek alphabet (intermediate between the 5th and 6th), used as numbers; denoting respectively 600, 60 and 6; 666 as a numeral:--six hundred threescore and six.
